To all whom it may concern:

Be it known that LAUGUST E. HALBEnT, a citizen oi the United States, and a resident of Battle Creek, inthe countyfofCalhoun and State of Michigan, have invented anew and Improved Spraying Devicaoll which the 'following is a "full, clear, and exact description.

This invention relates to spraying devices and has particular reference to that type of devices adapted :tor connection to or juse with a flexible hose whereby there may be mixed with the water being sprayed a soluf` tion of any desired nature such as insectieide, fungicide or fertilizer. V

More definitely stated Iprovide forthe nozzle end of a water hose anovel type of sprayer including a valve for controlling the ilow of water, a1 compression chamber out of which and into the current of lwater any suitable chemical is adapted to beforced for intimate mixture with the Water, and also a special form of mixing chamber between the compression chamber and the spraying nozzle.

With the foregoing and other objects in view the invention consists in the arrange ment and combination of parts hereinafter described and claimed, and while the invention is not restricted to the exact details of construction disclosed or suggested herein, still for the purpose of illustrating a practical embodiment thereof reference is had to the accompanying drawings, in which like reference characters designate the same parts in the several views, and in Which Figure 1 is a side elevation of my improvemeut.

Fig. 2 .is a vertical sectional view on the line 2-2 of Fig. 1:, and

Fig. 3 is a vertical longitudinal section through the mixing chamber.

Referring now more particularly to the drawings I show an apparatus comprising a spraying member shown as a rose 10 con nected by a short tube 11 to the bottom of a substantially cubical form of mixing chamber or mixer 12, the inner end of the tube being projected at 11 to or beyond the center of the lower portion of the mixer. A removable cap 13 is provided at the bottom of the mixer for the purpose of Hushing or cleansing the same.

14. indicates another tube fitted `into the upper portion of the mixer and having its inner end 111 projected to `or beyond the vertical plane of the inner end of the'delivery tube 11, but in a horizontal plane spaced above said delivery tube. `Any materials delivered by the tube 14 into and through the mixer for delivery through the rose will be thoroughly agitated and mixed within the mixer because of the swirling effect pro duced bythe peculiar `arrangementiof the ends `oli the tubes within the mixer. f

At 15 I indicate `what I term herein as a compression chamber the same being adapted to contain, as indicated at 16, any desired materialsuch as a poison, fertilizer" or the like in any condition of fluidity adapting it to be forced or delivered downwardly throughahole 17 within a boss 18 4in which is carried loosely a ball valve 19 held in place bya disk ofgauze 20, or its equivalent, so that the ballwvill always `tend to seat promptly and `prevent water from entering the chamber 15. A short tube 21 extends from the boss 18 to a Tcoupling 22 secured to the tubell. At the top of the chamber 15 is a detachable cap 23 having a central hole 23 therein. A plunger 24 is slidably fitted within the chamber and is provided with a rack 25 projecting through the hole 23 perpendicular to the main portion of the plunger; The cap 23 having the hole as described constitutes a guide for the rack or stem 25. 26 indicates a pinion lixed upon an arbor 27 channeled in the bearings 28 on the outsidefof the cap. A wheel or finger piece 29 serves as a representation of means whereby the operator may easily apply force to rotate thel pinion and hence drive the plunger downwardly for ejecting the material 16, which may, for convenience, be ret ferred to hereinafter as a chemical. The plunger is fitted by any suitable gasket so as to be substantially iiuid tight and hence when the plunger is forced downwardly the chemical will be ejected through the hole 17 unseatingthe ball 19. This chemical therefore will be forced into the current of water and will be conveyed thereby into and through the mixer, and in the well mixed condition will be delivered from the rose, or its equivalent, to the plants or shrubbery.

Between the T 22 and the flexible hose 30 is a tube 31 of suflieient length to constitute a suitable hand hold and to accommodate a gate valve 32 or other equivalent means for controlling the flow of water through the device. A removable cap 33 is provided at thebottom of the compression chamber to facilitate the cleansing of the same.

An apparatus made in accordance with thisninvention is relatively cheap andeasyto manipulate. Furthermore it is effective'in operation and not liable to become out of order' or fail to perform its desired functions. The chemical inayibe introduced into the compression chamber either by unscrewingithecapand:removing the plu-nger or preferably fby unscrewing the cap 33. :For this latterpurpoee the device. obviously may beputupside down, the, gate valve 32 being shut. i t t l `'Ir claim 1. vA `Spraying device of the character described, comprising a mixing chamber, a tube :having a Straight endextending into the lower partof the mixingchambei toithe center thereof, `1and carrying a spraying member at its other end, a ,second `tube adapted to be connectedwith a Water Supply and having a straightend extending lintothe opposite` sideof the upper part of thelmixing chamber, to the center of said chamber, at chamber for containing a Aliquid `chemical having a valvecontrolled `outlet connected Withthesecoiid tube adjacentthe mixing chamber, and means for forcingthe liquid chemical into` the said second t tube ,i through said outlet. i

vthe mixing chamber as far as the center thereof at its lower side, al second tube fit# ted into the upper portion of the mixing chamber and having its inner eiidprojecting to `the center `ofthesame from the opposite side thereof, the ends of the tubes in the chamber being straightandfarra-nged in different horizontal planes, the said second tube being'iadapted to be connected Vwith aivater supply, and means Yfor forcing a liquid chemical Ainto the second tube. i i

`3. A spraying vdevice ofthechlaracter described, comprising a tube ivith'ivhich a hose is adapted to be connected, a valve to control theilowv of -ivater through-the tube, `a T t-coupling `connected withsaid tube, a compres-` sion Ichamber ,connected `to ithe ,T-`coupling said comprcseion chamber having `a hole in the center of'itsfbottom, aball valve below they hole of the chamber and preventing `ivater from the tube enteringthe chamber, a plunger/fitted Within the chamber and including arackashapedetem guided through the ieniovaibletop of tliechamber, a pinion journaledin bearings on the outsidelof the cap and `meshing'with the rack, and means to rotatelthe pinion.
